About

I am a mathematical engineer with a background in computational modelling, statistical learning and scientific computing. My recent academic work focused on data-driven surrogate modelling for street-scale NOx concentration prediction, combining simulation-derived data, meteorological variables and statistical methods.

I completed my MSc in Mathematical Engineering at Politecnico di Torino, with a research internship at École Centrale de Lyon. My interests include urban air quality modelling, environmental data analysis, surrogate modelling, optimization, computational physics and reproducible research workflows.

Scientific research

Street-scale NOx concentration prediction using surrogate models

2025

MSc thesis · Politecnico di Torino / École Centrale de Lyon

This project investigated data-driven approaches for predicting street-scale passive scalar concentrations using simulation-derived inputs from the SIRANE model. The work focused on dataset construction, feature engineering and the comparison of statistical and machine-learning models for concentration prediction at local urban scale.
